All the dreams that are lined out won’t necessarily come true, but
even you should know this
Because even the sky that looks like it’s about to break
is something that I have accepted
It’s okay A kind lie I want to grow up [1]

Do your best, do your best Set your life on fire
Keep on living in the reality that is still going on
Do your best, do your best During those days that are limited…
Make flowers bloom [2]

If you stretch your hand out to the aspirations that lay beyond hope
then tomorrow, fumble around and you’ll find them
I’ve come to understand what they mean
when they say that because it is fleeting, it’s beautiful
I’m sorry Just a little bit more I’ll grow up [1]

Do your best, do your best Winning and losing are
actually important things aren’t they
Do your best, do your best That’s right, life isn’t something you can do over

Because when sometime later you look back
the “younger days” of today will
certainly become something reminiscent

Do your best, do your best Set your life on fire
Keep on living in the reality that is still going on
Do your best, do your best During those days that are limited…

[1]大人になる/なりたい (otona ni naru/naritai) – literally means to (want to)
“become an adult/grow up” but it also has the underlying meaning of
“maturing.” So don’t read this as just physically growing up, but
mentally (as in “growing in experience”) as well.

[2]花を咲かせる (hana wo sakaseru) – literally means to make flowers bloom,
but is more often used as an expression in the Japanese language that
means “to become successful”/”to bring something to cultivation.” So
she’s basically saying that during the limited days, while you’re still
young, do your best to become as successful as you can.
